Location:
Cambridge – Hybrid Preferred/Remote UK Considered (with ocassional travel to customers)
This is a genuinely hybrid technical role combining customer-facing SaaS implementation, software configuration and customisation, complex application support and hands‑on Java software development.
You’ll join a small, collaborative team, working directly with customers to implement, integrate and support a sophisticated SaaS platform, while contributing to software development and product enhancements.
With approximately 60% focused on technical implementation and customer enablement and 40% on software engineering, this role is ideal for someone who enjoys solving complex technical problems, writing code and taking ownership in a fast-moving start-up environment.
Key skills required for the Technical Implementation & Software Engineer
- Experience implementing, configuring, customising and supporting complex B2B SaaS software applications.
- Strong customer-facing technical experience, including requirements gathering, software implementation and stakeholder management.
- Experience in application support, incident management, troubleshooting, debugging and root cause analysis.
- Hands‑on Java development experience, ideally with some exposure to Spring Boot, Micronaut or similar frameworks.
- Understanding of APIs, third-party integrations, microservices and modern software architectures.
- Exposure to some of the following would be advantageous:
- AWS, cloud infrastructure and CI/CD
- Kubernetes, Docker or containerised applications
- Kafka and event-driven architectures
- IoT, connected devices or hardware engineering
- Strong problem‑solving and communication skills, with a proactive, adaptable approach suited to an early-stage start-up.
You don’t need to tick every technical box. We’re particularly interested in candidates who combine customer-facing SaaS implementation and support experience with practical Java development skills and a willingness to learn.

- Implement, configure and customise a complex SaaS platform to meet customer requirements.
- Work directly with customers and third-party partners to deliver technical implementations and integrations.
- Troubleshoot complex application issues, manage incidents and support production environments.
- Write, modify and test Java code, contributing to integrations, bug fixes and new functionality.
- Collaborate with Software Engineering and Product teams on development, testing and continuous delivery.
- Build and support APIs, third‑party integrations and connected IoT devices.
- Contribute to platform reliability, technical improvements and product development based on customer feedback.
Why this role?
- Early-stage start-up – join a small, ambitious team where your contribution will have a genuine impact.
- Implementation meets engineering – a unique 60/40 blend of customer-facing technical delivery and hands‑off
- Modern technology – work with Java, cloud technologies, microservices, CI/CD and IoT.
- Ownership and influence – help shape the product, solve real customer challenges and contribute to the company’s growth.
